Yet most people spend nearly as many waking hours with their colleagues as as they do with their partners/family. I've never understood this attitude, you just make it harder for yourself and those you work withffs do like I do .. I work with them why the **** would I want to eat with them/you ...
it's a job not a social gathering ..

I'm not saying you have to be a social butterfly and out drinking twice a week with your team, but you'd be surprised what a single team lunch or couple of beers after work can do to help the wheels turn more easily.
